The LOCK class record contains data describing the operation of the lock management subsystem. The LOCK class record has a record type of 7 and a size of 56 bytes.

Figure H-15 illustrates the format of the LOCK class record.

Figure H-15 LOCK Class Record Format

The following table describes the fields in the data block for the LOCK class record:

The MODES class record contains data describing time spent in each of the processor modes. The MODES class record has a record type of 2; its size depends on the number of active CPUs on the system being monitored. The size, in bytes, is calculated by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formula, which assumes that all CPUs are active:

16 + 8 + (36 * MNR_SYI$B_MPCPUS) 

Figure H-16 illustrates the format of the MODES class record.

The following table describes the fields in the data block for the MODES class record:

The MSCP_SERVER class record contains data describing activities of the MSCP server. The MSCP_SERVER class record has a record type of 21 and a size of 68 bytes.

Figure H-17 illustrates the format of the MSCP_SERVER class record.

The following table describes the fields in the data block for the MSCP_SERVER class record:

The PAGE class record contains data describing the operation of the page management subsystem. The PAGE class record has a record type of 3 and a size of 68 bytes.

Figure H-18 illustrates the format of the PAGE class record.

The following table describes the fields in the data block for the PAGE class record:

The PROCESSES class record contains data describing all processes in the system. The PROCESSES class record has a record type of 0; its size depends on the number of processes being monitored. The size, in bytes, is calculated by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formulas:

13 + 8 + (67 * the value of MNR_CMP$L_ELTCT) in OpenVMS Alpha Version 7.3-2 
 
16 + 8 + (72 * the value of MNR_CMP$L_ELTCT) in OpenVMS Alpha Version 8.2 
                                                    and Integrity servers Version 8.2-1 
                              
16 + 8 + (96 * the value of MNR_CMP$L_ELTCT) in OpenVMS Alpha and Integrity servers 
                                                    Version 8.3 
 

Figure H-19 illustrates the format of the PROCESSES class record on Alpha and Integrity servers.

The RLOCK class record contains data that is useful for monitoring the dynamic lock remastering statistics of a node. The RLOCK class record has a record type of 27 and a size of 44 bytes.

Figure H-20 illustrates the format of the RLOCK class record.

The following table describes the fields in the data block for the RLOCK class record:

The RMS class record contains data describing Record Management Services for specified files. The RMS class record has a record type of 20. Use the following formula to calculate the record size (the formula calculates the size by adding the size of the class header, the class prefix, and the data blocks contained in the record):

16 + 8 + (276 * MNR_CMP$L_ELTCT) 

Figure H-21 illustrates the format of the RMS class record.

The following table describes the fields in the data block for the RMS class record:

The SCS class record contains data describing SCS (System Communications Services) activity for all SCS connections in the system, on a per-node basis. The SCS class record has a record type of 15; its size depends on the number of nodes being monitored. The size, in bytes, is calculated by adding the size of the class header, the class prefix, and the data blocks contained in the record. This is shown in the following formula:

16 + 8 + (56 * the value of MNR_CMP$L_ELTCT) 

Figure H-22 illustrates the format of the SCS class record.
